topping up in Oshawa

Just need some information where I can charge up in Oshawa. I will be deployed to Oshawa downtown core (where King St W joins King St E) for sometime (say 6 month) starting next week. I am commuting from Richmond Hill. One way distance is 60KM. Although the distance is a piece of cake for my 90D to manage, I'd still like to have somewhere to have my car plugged in as winter is looming. Anyone can shed some light where I can plug in during business hours? Even 110V should be fine and I don't mind if I have to walk for 20 minutes after dropping the car.
